To achieve improvement in initial conversion efficiency of solar cell modules, inhibition of deterioration in transparency of a resin, inhibition of degradation in adhesive properties with respect to a protective member over time, and inhibition of degradation in conversion efficiency. A resin composition for solar cell-sealing material according to the present invention includes an ethylene copolymer, and further includes at least one of: (i) a compound represented by the following general formula (1); (ii) a calcined product of the (i); (iii) a compound represented by the following general formula (2); and (iv) a calcined product of the (iii). The (i) has an average plate surface diameter of 0.01 to 0.9 µm and a refractive index of 1.45 to 1.55, and the (iii) has an average plate surface diameter of 0.02 to 0.9 µm and a refractive index of 1.48 to 1.6. General formula (1): Mg 1-a ·Al a (OH) 2 ·An n- a/n ·bH 2 O (0.2‰¤a‰¤0.35, 0‰¤b‰¤1, An: an n-valent anion); General formula (2): (M c Mg 1-c ) 1-d ·Al d (OH) 2 ·B m m- d/m·eH 2 O (M represents a metal selected from the group consisting of Ni, Zn, and Ca; c, d, and e are respectively expressed as 0.2‰¤c‰¤1, 0.2‰¤d‰¤0.4, and 0‰¤e‰¤4; Bm: an m-valent anion).
